Color in ambient mode for Ksana Sweep users

Got quite a few requests to add color to the different ambient/dimmed modes on Ksana Sweep watch face. I’ve been a bit stubborn and refused to make this change because I believed it would hurt battery life and perhaps be hard to implement without risking burn-in on users watch screens.

I was wrong (to my defence the ambient mode documentation available is bit confusing and contradictory).
